New features

[#33] the toolchain prefix for Linaro AArch64 bare-metal ELF was updated from aarch64-none-elf- to aarch64-elf-; the change is effective for newly created projects; old projects require to reselect the toolchain for the update to be effective.

Addressed bugs

none.

Template issues

in certain conditions, the linker complained about a missing symbol (__dso_handle); added as weak to _syscalls.c.

Other changes

none.

Known problems

due to a copy/paste error, the default selection for the F7 processor is wrong and projects apparently configured for STM32F745xx are actually for the non-existing STM32F707xx and the build fails; the problem was fixed in the 2.11.1 release; as an workaround, explicitly select the processor even for STM32F745xx; fixed in 2.11.1-201512141335.
